Sacramento Water Department Report
Louis D. Ehret, superintendent of the water department of Sacramento, Cal., has submitted his annual report to the commissioner of public works of that city. Following is the substance of the report:
There was pumped from the city water works during the past year 5,192,658,320 gallons of water, as compared with 4,952,050,120 gallons for
1911. The cost of pumping station expenses amounted to $27,890.02, as compared with $32,-344.40 for the previous year. The total average daily consumption of water for the vear amounted to 14,187,591 gallons, as compared with 13,-568,921 gallons for 1911. based upon an estimated population of 40,000, the above figures represent a per capita consumption of 308 gallons daliy for
1912, and 301.5 gallons for 1911. During the month of January. 1912. this being our lightest pionth, we pumped the following: Total gallons, 358,104,350; average gallons per day, 11,551,753; gallons per capita. 46,000 population, 251. During the month of August, 1912, this being our largest month, we punjped the following: Total gallons, 542,795,070; average gallons per day, 17,-509,518; gallons per capita. 46,000 population, 380. The pumping station of the water works department last year reached its full capacity, and during irrigation hours it was impossible to get the required 60 pounds fire pressure. I recommend that Section 36. of Ordinance No. 707, be enforced, which is as follows:
“Section 36.—It shall be unlawful for any person or persons to open any hydrant, except for fire purposes, after an alarm of fire Is made, or to use any water from any hydrant, either for street sprinkling or irrigation, during the progress of a fire; and all hydrants that may be open for either of the above purposes when an alarm of fire is made must be immediately closed by the person who opened them, or have them in charge, and not again opened until the fire (if there be one) is ext nguished.”
Every person served with city water should see that their plumbing is in good order, but they do not, as is shown by our large water consumption. The city should not be using more than an average of 150 gallons per capita, or 7,500,000 gallons per day. This would mean a saving of about $9,000 per year, and to accomplish this I would recommend a house-to-house inspection of all plumbing. In order to avoid the heavy drawing of water during irrigation hours, I recommend that the street sprinkling be done between the hours of 3 a. m. and 7 a. m., and 12 m. to 4 p. m. This would allow the water works to maintain a better pressure in the residence district during irrigation hours.
